The development of distributed computing technologies and BigData in LIT-JINR

The main activities of the Laboratory of Information Technologies (LIT) of the Joint Institute for Nuclear Research (JINR) are addressed with emphasis on the development of distributed computing. The contribution of the LIT staff to the development of computational models for experiments done at the Large Hadron Collider (LHC) at CERN is briefly described. A brief overview is given of projects devoted to the development of distributed computations with LIT involvement in Russia, CERN, the USA, China, JINR Member States. Particular attention is devoted to the creation of a CMS Tier1 center in JINR and the development of computational models for the mega-project NICA. The report ends with the LIT work on the integration of the HPC, grid, cloud, and BigData technologies in large scale international projects
